Stephen Hazell-Smith (Chairman 2005-2009) PLUS Markets Group was a UK electronic stock exchange based in London for small cap companies.

PLUS Market Group was the holding company for PLUS Stock Exchange (PLUS-SX), PLUS Derivatives (PLUS-DX) and Plus Technology (PLUS-TX).

The group gained the gold standard recognised investment exchange (RIE) licence in July 2007 but struggled to make much headway against the dominant LSE.

Although it did host some well-known names, including Arsenal Football Club it failed to break even and the group eventually got into financial difficulty in 2012.

In 2009 Brickles and Hazell-Smith stepped down and were replaced by Cyril Theret, formerly the business development director at PLUS, and Giles Vardey as chairman.
